I know PhpStorm is the most useful IDE for Php development. It is written in Java so before the installation you need to install JRE/JDK on you system. Firstly, we download latest version of Oracle JDK/JRE from http://www.oracle.com/ which has tar.gz suffix according to our OS version 32 or 64 bit. In my old  post I have described how to install tar.gz in ubuntu.

Now you should download latest version of Phpstrom from here. Then extract archive file to /opt/ folder by using command below.

sudo tar -zxvf jdk-7u4-linux-i586.tar.gz -C /opt/
Then go to binary folder of PhpStorm and run it by using command below.
sudo /opt/PhpStrom-133.982/bin/phpstrom.sh

It will ask you details about licence and to create shortcuts. I suggest to create shortcuts because the biggest problem of Ubuntu. there is a few program that provide own shortcut. By google I found some phpstorm 7 license key free crack and working properly.
